Pass on some useful advice or information you learned and always remembered.
Never take life for granted.
Never let an opportunity pass you buy.
Live in the moment and take every ounce of those moments in.
All the while, never lose your sense of wonder.
The best advice I was ever given came from a song. Cliche, I know. When I was in middle school, I heard "The Dance" for the first time. It stopped me dead in my tracks, as it still does to this very day. No matter how many times I've listened to it over the years, I continue to get chills. I think it's safe to assume you've all heard this song. If not, I'm sorry your life sucks.
To put it simply, the song is about how even though things have to come to and end and things might hurt, it's no reason not to get out there and enjoy the time we have while we have it. We should live without fear and reservation. Instead, get out there and learn to dance, dance like you don't have a care in the world. Take in every spin, celebrate the changing melodies, and don't worry about when or how the song will end.
